Rails - Mar 2007 - Can't update tbody in IE 6 with page['name'].replace_html

Can anyone verify that you can''t update a tbody element in IE 6 by
using
page[''name]''.replace_html?

I''ve tried all three ways I know to update the innerHTML property of
the
tbody and it won''t take.

But page[''name''].insert_html works fine.

Just look for corroboration.

Thanks,
Wes

It''s true for all IE versions.  IE uses MS Table DOM, not the W3C DOM. 
There''s an explanation on MSDN.  You can replace a tbody, you can
insert
another tbody above or below, but you basically can''t do anything via
Ajax
with an existing <tbody> or <tr>.  I think you can update a
<td> if that
does anything for you.  Not 100% sure of all the caveats on that though.

hth,

I guess this was why I got that error with the Dojo FilteringTable on
IE.

What I needed to do was to replace a whole set of rows (in a datagrid) 
with another set.

Luckily, IE does follow DOM level 2 (at least for what I needed), and I 
solved my problem by deleting each row from the bottom up (you have to 
do it from the bottom up or the relative indexing of rows within the 
<tbody> element will change), and then doing a
"page.insert_html" to the
bottom of the tbody (which will at that point have no rows in it).

It is a pain in the arse, but it does work in both IE and FF. 
XSLDatagrid::ROWS_TO_DISPLAY is the number of rows in the tbody named 
xdgRowSet_thingy.

Here''s the code:

render :update do |page|
  (0..XSLDatagrid::ROWS_TO_DISPLAY - 1).to_a.reverse.each do |index|
    page << 
"$(''xdgRowSet_#{XSLDatagrid::CONTAINER_ID}'').deleteRow(#{index});"
  end
  page.insert_html(:bottom, "xdgRowSet_#{XSLDatagrid::CONTAINER_ID}", 
output)

...other stuff...
end

I have such mixed feelings about this project, it causes me so much 
grief but then I always end up learning something useful by overcoming 
all these ridiculous f-in'' problems ;).
